Keluhan muskuloskeletal terjadi karena adanya pembebanan yang cukup berat dan berulang (repetitif) yang menyebabkan otot mengalami kontraksi secara berlebihan sehingga melebihi kekuatan otot maksimum. REBA (Rapid Entire Body Assessment) adalah metode sistematis yang mengevaluasi seluruh postur tubuh pekerja untuk mengidentifikasi resiko keluhan muskuloskeletal dan resiko lain yang berhubungan dengan pekerjaan. Petani bawang merah di Kecamatan Dringu menjelaskan bahwa mereka merasakan keluhan nyeri pada bagian leher, pundak, lengan kanan, pinggang dan kaki. Posisi kerja saat mereka bekerja adalah berdiri dengan posisi punggung membungkuk dalam suatu periode tertentu. Tujuan penelitian ini untuk menganalisis postur kerja dengan metode REBA dan mengetahui keluhan subjektif muskuloskeletal yang dialami oleh petani bawang merah di Kecamatan Dringu, Probolinggo. Desain penelitian ini adalah penelitian deskriptif dengan pendekatan cross sectional. Hasil penilaian postur kerja dengan metode REBA menunjukkan tingkat resiko tinggi terjadinya keluhan muskuloskeletal pada seluruh responden (100%) yang masa kerjanya >10tahun. Seluruh responden dengan masa kerja >10tahun dan seluruh responden dengan usia >35tahun memiliki keluhan subjektif muskuloskeletal yang lebih banyak. Petani disarankan dapat melakukan peragangan otot sesaat sebelum melakukan aktivitas kerja dan mengatur waktu istirahat sesuai standart yaitu 15% - 30% dari seluruh waktu kerja.

Work fatigue is one of health and safety problems which can be risk factor for workplace accidents. There are many factors that cause work fatigue, like age, gender, work load, working period, and carbonmonoxide exposure. The objective of this study was to identity the carbon monoxide exposure in blood and workers characteristic on work fatigue in the fum fish village Penatarsewu Sidoarjo Regency. The research was using cross sectional design with 42 samples. Work fatigue was quantified with reaction timer carbon monoxide effect with measuring COHb level in blood, work load with fingertrip oximeter, and workers characteristic were collected through interview with questionnaires. Study was analyzed with multivariate logistic regression through SPSS. The research shows analysis suggests that age and sex aren’t significantly related to work-related fatigue, while employment period, work load and Carbon Monoxide exposure are significantly related to work-related fatigue. The result of multivariate analysis shows that work load, employment period and Carbon Monoxide exposure are significantly related to work-related fatigue. Work load is the dominant variable for work-related fatigue. Workers having heavy work load are exposed to work-related fatigue 9 times higher compared to those with light work load.

Background: In our current times, to communicate risks effectively with populations, communities, families and individuals is essential for everyone to be better prepared when disaster and crisis hit. The purpose of this study was to determine the different effecttiveness of safety media on knowledge, attitude, and self-efficacy in disaster preparedness among visitors at a hospital. Subject and Methods: This was a quasi-experiment conducted at a hospital in Semarang. A sample of 33 hospital visitors was selected for this study and divided into three groups: leaflet group, video group, and leaflet-video group. The dependent variables were knowledge, attitude, and self-efficacy in disaster preparedness. The independent variable was safety media. The data were collected by questionnaire. The data were analyzed by Oneway ANOVA and posthoc test. Results: Mean score of knowledge in the leaflet-video group was higher than the remaining two groups, and it was statistically significant. Differences in mean score of attitude and self-efficacy between the three groups were statistically non-significant. Conclusion:Leaflet-video is the most effective safety media to improve knowledge in disaster preparedness. Leaflet, video, and its combination do not make difference to change attitude and self-efficacy.
